Q1: Will this work with my TV?
Yes, if the TV has a working Optical/TOSLINK or 3.5 mm AUX audio output. For Optical, set the TV audio format to PCM or Stereo.
Q2: Can I keep my TV speakers on?
It depends on your TV settings and speaker placement. When the Harmony A2 is used close to the TV, the small timing difference between the two audio paths may create an audible echo. If this happens, mute the TV's built-in speakers or move the Harmony A2 farther away from the TV.
Q3: Can I adjust the speaker from my seat?
Yes. Use the controls on the Harmony A2 speaker to change its volume and EQ mode.
Q4: Can I use the Harmony A2 speaker without the transmitter?
Yes. It can connect directly to a compatible phone, tablet, or computer through Bluetooth.
Q5: Can more Auracast devices listen to the TV?
Yes. Additional compatible Auracast receivers can join the Audikast 4 broadcast. Compatibility varies by device.
Q6: Does the transmitter support HDMI?
No. Audikast 4 accepts Optical/TOSLINK or 3.5 mm AUX audio; an HDMI-only TV requires an additional audio extractor.
